## Overview

The Arbor Scientific Project Star Precision Spectrometer is a compact, durable plastic instrument designed for STEM education. Featuring a diffraction grating and dual-scale measurement in nanometers and electron volts, it enables precise identification of spectral lines from various light sources. With an integrated spectral chart and a detailed teaching guide, it’s ideal for high school to college students exploring physics, chemistry, and astronomy. Trusted by educators for its balance of affordability and accuracy.

## Description

Now students can see absorption lines in the sun’s spectrum with this spectrometer developed at the Harvard Center for Astrophysics’ Project STAR. With actual wavelength measurements and equivalent energies in electron volts, this tool enables students to identify different elements in various light sources, such as fluorescent lights, incandescent light bulbs, gas tubes, sodium or Mercury vapor lights, etc. They will be able to see the double yellow line of Mercury vapor in the spectrum of a fluorescent lamp. Light pollution can be studied by checking yellow street lights to see if they are high- or low-pressure sodium lamps. The spectrometer comes with a strip of film that includes the slit and a scale from which a color may be identified by wavelength in nanometers or photon energy in electron volts. Activities include: observing what diffraction grating does, calibrating the spectrometer, and identifying various light sources. Durable plastic construction. Recommended for astronomy, chemistry, physics, physical science, and earth science from high school to college

Review: By far the best spectrometer for the price - It's meant for school experiments. It's plastic. It feels like a toy. But it's vastly better than all the other under $100 spectrometers on the market. The original 1991 version had an adjustable scale so you could calibrate out any scale error. This one still mentions that on a sticker, but the scale is NOT adjustable. Mine reads low by about 1.5 nanometers. You have to squint to use it; it's awkward. But if you're careful you can read lines to the nearest 1 or 2 nanometers. The EICO and all the other ones I've seen (I think I bought all of them) are worse. This one is not great, but it's by far the best for less than $100. Nothing else is even close. Update 2024-11: Google on the "little garden spectrometer". It's a electronic gadget, doesn't cost much more than this, and is vastly more capable. With that one you read the spectrum on a computer screen.
Review: This actually works - The instructions are very poor and if you do not have prior knowledge of how to use it you may struggle to figure it out. Point the instrument at a light source and rotate the grating until the refracted light illuminates the scale in the instrument.

### ⭐ Awkward to use. Never able to demonstrate satisfactory performance.
*by C***. on March 9, 2020*

I intended to use this spectrometer to have my grandson learn about the spectrum of light. To use it you aimed the slit side at the light source and then looked away to the left to see the spectrum. This was awkward with the hand held spectrometer as I would lose the aim to the light source. It seemed impossible to ever keep a small light source aligned. I would not want my grandson to try to use it and get fustrated. There was no focusing that I found so I had to look through the close up part of my tri-focals to try and focus on the spectrum. The lines did not look too sharp. ?? Hard to use and I quit after 30 minutes of trying to optimize its use. Minimal instructions for using the spectrometer.
